--- Comment #13 from John Doe <bau2wux4sh at pkv73 dot anonbox.net> --- (In reply to Andrew Pinski from comment #12) > Because the Linux-gnu folks will always use lib64 instead of lib here. So > there is no need to fix gcc/config/riscv/t-linux. There is a LSF on purpose > which I thought defined this all for *-*-linux-gnu across distros. What is LSF? Do you mean LSB (Linux Standard Base)? Because the comment in the t-linux64 i386 configuration file explicitly states: > The LSB does not enforce the use of /lib64 and /usr/lib64 I might be repeating myself but other architecture configuration files explicitly include a check to ensure that this directory exists, e.g.: > $(if $(wildcard $(shell echo > $(SYSTEM_HEADER_DIR))/../../usr/lib32),../lib32,../lib) Then again I am personally not very familiar with these configuration files, it just seems odd to me that the RISC-V one doesn't have such a check.
